Higher requirements concerning economical aspect of the production of induction motors encourage designers to look for new variants of motor construction. The small induction motors with stator core shape with cut of parts making stator yoke width not constant is an example of an atypical motor construction. The subject of this paper is a field-circuit and circuit analysis of this type of motor construction. The aim of this analysis is to determine the influence of the saturation of the magnetic circuit on motor parameters. It is shown that the cuts of the stator core have significant influence at standstill and less significant at load characteristics of induction motors. Comparisons with measurements are given. From comparisons between the results of the analysis and experiments, it is clarified that the use of presented circuit and field-circuit methods can estimate characteristics of induction motors with enough accuracy even for motors with specific construction like not round stator core.
